I didn't do it when i was in college, but looking back i think i shoulda tried to join one.

It gives you a good group of people that will be your friends for at least those 4 years of school.

And some of the people i know who were in frats (my roommate from freshman year, and this other kid) still talk to some of their frat bros.

And of course, you get automatic access to the parties and you get to invite people in for free...which gives you power and automatically makes you the Shit, so then everybody wants to get to know you.
